摘要
采用先进的PLC控制技术和光电编码器检测技术对JL-30 000落锤冲击试验机继电器—单片机的控制模式进行升级改造,改造后仪器以触摸屏作为终端操作机,通过PLC进行采集脉冲计数、控制落锤提升、冲击等试验的全过程。
The relay--single hoard computer control system of JL--30 000 J Drop Weight Impact Testing Machine has been upgraded and revamped by using advanced PLC control technique and photoelectric encoder detecting technique, The revamped instrument uses touch screen as operation terminal, collects impulse signals for counting and controls the whole testing process of drop weight lifting and impacting with PLC.
